What is a hypernova explosion?
Hypernovas are the most powerful supernova explosions in the universe, 10 to even up to 100 times brighter than a typical supernova.
Has there ever been a hypernova?
The first hypernova observed was SN 1998bw, with a luminosity 100 times higher than a standard Type Ib. This supernova was the first to be associated with a gamma-ray burst (GRB) and it produced a shockwave containing an order of magnitude more energy than a normal supernova.
Is a hypernova stronger than a supernova?
A hypernova — sometimes called a collapsar — is a particularly energetic core-collapse supernova. Scientists think a hypernova occurs when stars more than 30 times the mass of the Sun quickly collapse into a black hole. The resulting explosion is 10 to 100 times more powerful than a supernova.
What is the most powerful hypernova?
SN2016aps
Now, researchers have announced the discovery of SN2016aps — the brightest, most energetic and probably the most massive supernova ever observed, reports Ryan Mandelbaum for Gizmodo. Supernovae are huge explosions caused by the deaths of stars at least five-times the mass of our sun, according to NASA.
What is stronger than a kilonova?
Supernovae are brighter and more luminous than your average kilonova where the latter is said to be 1/10th – 1/100th the brightness of a supernova if not less. Unlike a kilonova, your average supernova is able to outshine entire galaxies due to the magnitude of its luminosity.
Is a kilonova bigger than a supernova?
Supernova explosions are far bigger than those produced by a kilonova explosion due to the former ejecting more energy than the latter.
Can a hypernova destroy a galaxy?
Yes, supernovae can definitely have an influence on the presence of life in galaxies. They can destroy life not only on planets around the stars going through the explosion, but also on planets of neighbouring stars.
What if a gamma-ray hit Earth?
With the gamma-rays beamed directly at Earth, the radiation would destroy a significant portion of our atmosphere, specifically the ozone layer. The photons streaming from the burst would cause chemical reactions leading to photochemical smog. This would further deplete our protection from cosmic rays.
